DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 shows an isometric perspective view of a top portion 2 and a bottom portion 10 of a modified pizza box 1 in accordance with an embodiment of the present invention, with a full pizza 100 shown on a floor of the bottom portion 10 and with the bottom portion 10 of the modified pizza box 1 shown in a completely open state. The full pizza 100 includes eight slices, including slice 100 a. The top portion includes sides 2 a, 2 b, and 2 c and top 2 d. The top 2 d is connected by attachment device 2 e to a rear side 14 of the bottom portion 1 0. The attachment device 2 e may be a line or substantially linear section of perforated material, running from side 2 c to side 2 b along the periphery of top 2 d, which allows the top portion 2 to be easily detached from the bottom portion 10.

FIG. 2 shows an isometric perspective view of a bottom portion 10, after the top portion 2 has been detached, with the bottom portion 10 shown in a completely open state. FIG. 3 shows an isometric perspective view of the bottom portion 10 of the modified pizza box 1, with the bottom portion 1 0 shown in a partially closed state. FIG. 4 shows an isometric perspective view of the bottom portion 1 of the modified pizza box 1, with the bottom portion 10 of the modified pizza box 1 shown in a completely closed state. FIGS. 5-10 show top, left side, bottom side, right side, rear, and front views of the bottom portion 10 of the modified pizza box 1.

The bottom portion 10 of the modified pizza box 1 includes sections 12, 30 and 40. Section 12 includes walls 14, 18, and 20. Section 12 also includes overlap portions 16 and 22. The wall 14 includes front surface 14 c, shown in FIG. 2, and rear surface 14 d shown in FIG. 3. The wall 14 also includes notches 14 a and 14 b. The walls 18 and 20 are connected to overlap portions 16 and 22, respectively. Each of the overlap portions 16 and 22 are parallel to and overlap a portion of wall 14. Section 12 also includes a floor 11 having a top surface 11 a, shown in FIG. 2 and a bottom surface 11 b shown in FIG. 4.

The section 12 is connected to the section 30 by attachment device 36 b, which may be a fold, crease or line having a thinner material than floors 11 or 31, so that the section 12 can be easily folded from the fully opened state of FIG. 2 to the partially opened state of FIG. 3. The section 30 may include walls 32 and 34 and a floor 31. The floor 31 may have a top surface 31 a, shown in FIG. 2, and a bottom surface 31 b shown in FIG. 7. The section 30 may include lines of perforations or notched lines 32 a, 32 b, 34 a, and 34 b. The line of perforations 32 a allow the wall 32 to be easily detached from the wall 42, and the line of perforations 32 b allow the wall 32 to be easily detached from the wall 20, so that the wall 32 can be folded in towards floor surface 31 a or outwards. Similarly, the line of perforations 34 a allow the wall 34 to be easily detached from the wall 50, and the line of perforations 34 b allow the wall 34 to be easily detached from the wall 18, so that the wall 34 can be folded in towards floor surface 31 a or outwards. With the walls 34 and 32 detached, the section 12 can be folded over from the state in FIG. 2 to the state in FIG. 3, or to the state in FIG. 4.

The section 30 is connected to the section 40 by attachment device 36 a, which may be a fold, crease or line having a thinner material than the floors 31, or 41, so that the section 30 can be easily folded from the fully opened state of FIG. 2 to the fully closed state of FIG. 4. Section 40 includes walls 42, 44, and 50. Section 40 also includes overlap top section 46 and overlap wall 48. Walls 44 and 48 includes semicircular notch 44 a and 48, respectively. Wall 44 includes protruding sections 44 b and 44 c.

The section 40 also includes insert walls 43 and 53 which are connected to walls 42 and 50 , respectively. The insert walls 43 and 53 are substantially perpendicular to the floor 41 and lie between the walls 44 and 48. In this matter the walls 44 and 48 retain the walls 42 and 52 in an orientation which is substantially perpendicular with respect to the floor 41. Assuming the wall 32 is still connected to the walls 42 and 20 and the walls 50 and 18 are still connected to the wall 34, then the walls 42, 32, 20, 22, 16, 18, and 50 are also held in a substantially perpendicular orientation with respect to the floors 41, 31, and 11. However, when the wall 32 is separated from the walls 42 and 20 and the wall 34 is separated from the walls 50 and 18, by tearing or otherwise separating along perforations 32 a, 32 b, 34 a, and 34 b, the section 12 can be folded over the section 40, as shown by FIGS. 2, 3, and 4.

The wall 14 may not be held to the overlapping walls 22 and 16 and may fold outward away from the floor 11 a. Section 40 also includes a floor 41 having a top surface 41 a, shown in FIG. 2 and a bottom surface 41 b shown in FIG. 7.

In operation, a full pizza pie may be inserted into the chamber, recess, or opening 91 of the bottom portion 10, covering a portion of floor surfaces 41 a, 31 a, and 11 a. After some of the pizza has been eaten the bottom portion 10 can be transformed into a smaller container as follows. The wall 32 is separated from the walls 42 and 20 by tearing or otherwise separating along line of perforations 32 a and 32 b, respectively. The wall 34 is separated from the walls 50 and 18 by tearing or otherwise separating along line of perforations 34 a and 34 b, respectively. The walls 32 and 34, after separation, can then be folded outward or inward, so that the walls 32 and 34 may be substantially parallel to the floor surface 31 a, while the walls 42, 20, 50, and 18 remain substantially perpendicular to the floor surface 31 a.

After the walls 32 and 34 have been separated, and the walls 32 and 34 folded inwards or outwards, the section 12 can be folded from the state of FIG. 2 to the state of FIG. 3, along fold 36 b. Thereafter the section 30 can be folded along the fold line 36 a, to provide a completely closed smaller container, as shown in FIG. 4. The smaller container formed can more easily fit into a refrigerator than a typical pizza box.
